These architectural details illustrate aluminum stair expansion joints and hinge frame connections anchored to concrete or masonry substrates. The rotational joint assemblies incorporate an aluminum pan nosing, a continuous extruded aluminum modular plate, a deflector nosing, and a backer rod with sealant provided by others. The hinge frame details feature a continuous extruded aluminum hinge frame secured to the substrate with three-eighths-inch by two-and-one-half-inch zinc-finished screw bolts spaced at eighteen inches on center. A continuous extruded aluminum hinge nosing and exterior sealant complete the junction.
